HAPPY BIRTHDAY TO ALL WHO CELEBRATE TODAY

And now my problem
after I start my comp, when all icons are on desktop,a windows installer pops up and displays--configuring a bluetooth software.And than displays --error 1706.I have to cancel it before I am able to proceed.
TRIED SYSTEM RESTORE--NOTHING.
Removed all addins in outlook--nothing
Finally,run Hijackthis but Im afraid to remove anything--because I tried once and had to restore system

Is my computer infected?
Thanks,
Aku
